The Superflex SF-603 eyeglasses deliver practical, everyday durability in a clean square silhouette. Designed in Quebec and built from flexible acetate, these full-rim frames are engineered to handle the wear and tear of daily life without sacrificing comfort or style.
The SF-603 is crafted from cellulose acetate, a plant-based material that’s stronger and more flexible than standard injection-molded plastic. Acetate frames resist cracking, hold their shape over time, and won’t become brittle with age. The material is naturally hypoallergenic and lightweight, so you can wear them comfortably for extended periods. Available in three finishes—Matte Black (M300), Grey Crystal (S303), and Blue Stripe (S401)—the acetate construction delivers rich, fade-resistant color that lasts.
The square frame shape offers a versatile, modern look that suits most face shapes. The full-rim design provides excellent lens security and works particularly well for higher prescriptions, as the thicker rim conceals lens edges. With a 17mm bridge and available in 51mm and 53mm eye sizes, the SF-603 accommodates a range of fits. These frames are fully prescription-ready and compatible with single-vision, progressive, and high-index lenses.
At this price point, the SF-603 represents solid value for anyone seeking dependable, budget-friendly eyewear that doesn’t compromise on material quality. The flexible acetate construction means these frames can adapt to your face shape and withstand the occasional drop or bend—a practical choice for active lifestyles or as a reliable backup pair.
